Hello.
On my FreeBSD-box (FreeBSD xxxx.xxxx.xxxx 4.8-RELEASE-p13 FreeBSD
4.8-RELEASE-p13 #4: Tue Oct 14 19:19:51 EEST 2003
root@xxxx.xxxx.xxxx:/usr/src/sys/compile/DIALUP1 i386) I has been
confronred with some difficulties.
A ppp process is starting, working, finishing and then hangs, it stays
in memory and doesn't return control to mgetty after connection with
remote peer is lost.
In my log I see such records:
Nov 4 08:02:04 xxxx ppp[59631]: tun1: LCP: deflink: SendEchoRequest(187) state = Opened

And then also:
Nov 4 09:29:37 xxxx ppp[59631]: tun1: Warning: Packet too large (4102), discarding.
And after I tried to kill it with SIGTERM, I saw this:
Nov 4 10:39:23 xxxx ppp[59631]: tun1: Phase: Signal 15, terminate.
Nov 4 10:39:23 xxxx ppp[59631]: tun1: LCP: deflink: State change Stopping --> Closing

Nov 4 11:02:29 xxxx ppp[59631]: tun1: Phase: Signal 15, terminate.
Nov 4 11:02:29 xxxx ppp[59631]: tun1: Phase: Signal 15, terminate.
Nov 4 11:02:30 xxxx ppp[59631]: tun1: Phase: Signal 15, terminate.
SIGHUP is useless too:
Nov 4 11:03:24 xxxx ppp[59631]: tun1: Phase: Signal 1, terminate.
Nov 4 11:03:27 xxxx ppp[59631]: tun1: Phase: Signal 1, terminate.
Nov 4 11:03:28 xxxx ppp[59631]: tun1: Phase: Signal 1, terminate.
Nov 4 11:03:30 xxxx ppp[59631]: tun1: Phase: Signal 1, terminate.
All I can do with it - kill it with SIGKILL.
